[En-Nut-Discussion] IRQ on EIR board

[Thierry GRAUSS]

Hello,

I have (will receive soon) the EIR board. It will be used as a control board 
for
a preamplifier. I will then have to connect switchs and buttons to be able to
control my preamp.
The problem is that there are no IRQ lines available, so I can't wake up the 
CPU
when it is sleeping and I push on the push button to turn on or push a key of
the remote to wake up the preamp.
For other buttons, no problem, as I can implement a counter which will 
interrupt
the CPU, which will then check if a button is pressed. But when it is sleeping
(not using the preamp) ... it is not nice to have such behaviour.

Another solution might be to have a microcontroller to manage the user inputs
and this one turning of the EIR board when it should sleep, and turning on the
EIR when we push the ON button.

Does someone have a better idea on how to get arround this lack of interrupt
lines ?

Thanks

Thierry
